that sounds positive.

I never had a problem with heat from those CFLs, i got a blue and red one and both run pretty cool. I made my own reflector out the box they came in - just painted the inside flat white and fixed the sides to 45 degrees using thick wire, works a treat.

I grow in dirt and will be using clones and 24 sounds a good number. What sort of sized pots should I be using - 6" I guess is the maximum but seems too shallow.

I was thinking about using 2litre coke bottles 3.5" x 10". Any thoughts?

Thanks.
